First One UI 9 beta builds spotted

X users Kailash and Tarun Vats have both spotted the first One UI 9 beta builds for the Galaxy S26 series on Samsung’s servers (h/t: SammyFans).

Version numbers and target models

The builds have version numbers ending in ZZE7 and BZE7, and they appear to target the Galaxy S26 Plus and Ultra models.

Timeline comparison with previous cycles

This suggests Samsung is testing the software internally before a public beta release. In previous cycles, the first One UI 8.5 beta for the Galaxy S25 series appeared on Samsung’s servers in late November, with the public beta announced in early December. By that pattern, a public One UI 9 beta could arrive within weeks.

Upcoming stable One UI 8.5 rollout

The news also coincides with anticipation for the stable One UI 8.5 rollout on the Samsung Galaxy S25 phones. A tipster claims the update could land on May 8 or May 11 (source).
